The minimum perimeter of a polyomino is the perimeter of the most square shape that can be formed. If the area can't form a perfect square, the minimum is formed by wrapping the additional units in a spiral around the smallest square or rectangle. Since 25 happens to be a perfect square (the square root is 5), the perimeter would be 2(5+5)=20. If the area were between 26 and 30 that would add two additional sides which would be 20+2. After 30 the units would wrap to a new side of the 5x6 arrangement (still a perimeter of 22) yielding a new perimeter of 22+2 or 24, which would persist until it exceeds 6x6, and so on.

A "six sided shape" is a hexagon. The solid formed by 6 squares is a cube (four sides, top, bottom).
The answer is hexagon because if it is formed by curved, line segments, or both it is definitely hexagon!
A large compound formed by the joining of smaller compounds is called a polymer.
Diagonals in an hexagon: 0.5*(6^2 -3*6) = 9 diagonals

The three major diagonals in an ordinary hexagon do not intersect at the same point. Therefore, in such a hexagon, the diagonals form 111 triangles.
The statement is not generally true. It is true only for regular hexagons. Join the centre of the hexagon to three alternating vertices. You will have formed three rhombi in the hexagon.
